Leveling as SCH

I always been leveling my heal class (Scholar) in dungeons, one after another, and main quests with Summoner. But I'm starting in Stormblood and it requires more gear than the usual and my Summoner is not able to do quests, so I got to do them with SCH but seems difficult as I dont do much DPS. Can anyone give me a recommendation, or what should I do?

You could try doing dungeons with Smn to try and gear up, or buy gear for your Smn if you have enough tomes.

EDIT: You can also buy gear in SB for gil from vendors.

Can I know the place for that? Thanks
EDIT: Found it!
